The clinical effects of mobilization with passive ankle dorsiflexion using a passive ankle dorsiflexion apparatus on older patients with knee osteoarthritis: A randomized trial
Bibliographic record
Abstract
BACKGROUND: Active exercise is the only proven effective intervention for knee osteoarthritis (OA). The addition of manual therapy has shown to improve outcome of exercises. Passive mobilization with submaximal bilateral passive ankle dorsiflexion was examined in a double-blinded randomized controlled clinical trial. A passive ankle dorsiflexion apparatus was used to standardize the frequency, range of motion, and duration parameters. OBJECTIVES: The purpose of the study was to determine whether a simple standardised mobilization technique could be incorporated as a safe and unsupervised conservative treatment for knee OA. METHODS: In total, 73 participants were randomly assigned to the experimental (n= 37) or control group (n= 36). All participants performed active exercises and received six sessions of 10-minute dorsiflexion intervention, either real or sham, for two weeks. Pre- and post-experimental assessments for the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain, and range of motion of the knee were conducted. RESULTS: Results were analyzed using two-way repeated measures analysis of variance and Independent-Samples Mann-Whitney U Test. The mean score of WOMAC for the experimental and control groups changed from 31.84 to 18.19 and 34.74 to 21.06, respectively, after the intervention. The VAS also showed significant improvements. Significant improvements were observed in WOMAC in both groups after the intervention; however, differences between the groups were not statistically significant. CONCLUSIONS: Exercise with either 30∘ or 5∘ of passive dorsiflexion yielded favorable clinical effects. Although submaximal bilateral ankle dorsiflexion was proven to be safe for elderly participants with osteoarthritis of the knee, whether it provided extra benefits to exercises alone was unclear. Further research is required to determine the effectiveness of dorsiflexion and optimal range of mobilization.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
